The table provides information on three alternative fuels.

(See attached diagram)

The data in this table can be used as evidence to support the claim that all of these fuels–

• are very costly to produce.

• exist in the same state of matter.

• are made of natural materials.

• take several days to produce.

Plastics are created from processed petroleum which is pulled up from below the ground. This is important because–

• petroleum is a non-renewable resource.

• processing and using petroleum releases contaminants into the environment.

• plastic products are not biodegradable and pollute the environment.

• all of the above.
